Matsya-6000: India’s First Manned Deep-Sea Submersible – Key Facts for CDS, NDA & CAPF 2025

India is pushing the boundaries of deep-ocean exploration with the launch of Matsya-6000, the nation’s first manned deep-sea submersible. Developed under the Samudrayaan Mission and the broader Deep Ocean Mission, Matsya-6000 will enable direct human access to ocean depths of up to 6,000 meters.

What is Matsya-6000?

Matsya-6000 is a crewed submersible designed by the National Institute of Ocean Technology (NIOT), Chennai. It can carry three aquanauts to extreme depths of 6,000 meters, placing India among the few nations—like the US, Russia, Japan, France, and China—with such capability.

This mission is often compared with ISRO’s Gaganyaan mission in space, as both signify India’s dual exploration frontiers: space and ocean.

Latest News and Trials

• Matsya-6000 has undergone dry and wet trials at the L&T Shipbuilding facility near Chennai.

• It has successfully completed eight dives (both unmanned and manned).

• Next step: shallow-water trials up to 500 meters in 2025.

• Final goal: full-depth mission of 6,000 meters by 2026.

These trials tested its life-support systems, navigational control, and structural strength to ensure aquanaut safety during long-duration deep-sea missions.
